preg_match("/<head>(.*)<\/head>/i",$content, $matches);
匹配不到任何内容

eregi("<head>(.*)</head>",$content, $matches);

require_once("snoopy.class.php");
$snoopy = new Snoopy;
$url="http://www.sina.com.cn";
$snoopy->fetch($url);
$content = $snoopy->results;
preg_match("/<head>(.*?)<\/head>/is",$content, $matches);//这样应该可以了
print_r($matches);

总是抓不到东西，页面光光的，查看原码也是空的。

申明一下，不是大小写的问题。页面的原代码都是小写的。
实例：
"Any", "password"=>"Any", "ticker"=>$symbol);
// Call the webservice "doCompanyInfo" method with the arguments.
$results = $client->call("doCompanyInfo", $args);
/* $results is an array with the following structure
Array
(
